I'm using Meter for visual presentation and it now well calibrated (with tacho)
so it is showing accurate rpm-s.
What is happening is that when there comes ie. M3 S15000 gauge shoots instantly
to that value, so it doesn't follow acceleration that I programmed. So probably
spindle-cmd is not a "realtime" signal to use for presentation, also for
determination when spindle reaches desired speed and also used for triggering
motion.spindle-at-speed
